PREMIS Tables

Object Example:

Semantic Unit	Value
1.1.1 IdentifierType	filePath
1.1.2 IdentifierValue	file:///Users/username/Files/PoP/SampleVideo.mov

Notes: Students often find assigning standard identifiers to distinct sections of a PREMIS record quite challenging. Identification is the key to good metadata making: in order to aggregate and curate data about data, we have to know what we are about. PREMIS has a set of suggested controlled identifier types, available at the Library of Congress: https://id.loc.gov/vocabulary/identifiers.html. It is important to remember that these are suggested, rather than required. If there is an option in the controlled vocabulary that works, then standardization is almost always preferable. In the case of digital files, a local naming convention also works. We’ve used the file path in this example, because this is a toy example and because this data is provided in the DROID read out. However, we also acknowledge that file paths are not the best way to name things, as these identifiers break when content is moved: this is why we don’t name people after their addresses anymore!

Semantic Unit	Value
1.5.2.1 messageDigestAlgorithm	MD5
1.5.2.2 messageDigest	151e4e5a49f462ec673a707c30a20361
1.5.2.3 messageDigestOriginator	DROID

Event and Agent Example:

Semantic Unit	Value
2.1.1 eventIdentifierType	locallyDefinedIdentifier
2.1.2 eventIdentifierValue	Event1
2.2 eventType	fixityCheck | formatIdentification | messageDigestCalculation | metadataExtraction
2.3 eventDateTime	2021-07-12
2.6.1 linkingAgentIdentifierType	locallyDefinedIdentifier
2.6.2 linkingAgentIdentifierValue	Agent1
2.6.3 linkingAgentRole	Implementor | Executing Program
2.7.1 linkingObjectIdentifierType	filePath
2.7.2 linkingObjectIdentifierValue	file:///Users/username/Files/PoP/SampleVideo.mov
3.1.1 agentIdentifierType	locallyDefinedIdentifier
3.1.2 agentIdentifierValue	Agent1
3.2 agentName	[Your Name] | DROID
3.3 agentType	Person | Software
3.7 linkingEventIdentifier	locallyDefinedIdentifier
3.7.1 linkingEventIdentifierType	Event1

Note: There are many correct answers. The above suggestions are ones that could be reasonably inferred from the DROID output, but you can practice with others more closely related to your organization’s needs. In this case, pipes ( | ) separate discrete correct values for the same semantic unit.
